[0031] Referring to Figures 1 to 8 , an improved one-way access door, comprising a frame 100, the frame 100 being a quadrangular prism shape, a rotation area 110 and a secondary door area 120 being provided inside the frame 100, a revolving door body 200 being assembled inside the rotation area 110, an entrance and an exit being respectively provided in the front-rear direction of the rotation area 110, the secondary door area 120 being located on one side of the entrance, a secondary door body 300 being assembled inside the secondary door area 120, the revolving door body 200 having a door shaft 210 as the rotation center, the door shaft 210 driving the secondary door body 300 to reciprocate in the radial direction of the revolving door body 200 through a linkage mechanism, a one-way ratchet 211 being assembled on the door shaft 210, and an electromagnetic lock 130 being assembled on the frame 100 and cooperating with the one-way ratchet 211. The design of the one-way ratchet 211 and the electromagnetic lock 130 enables the one-way access door to have a one-way locking function. When locking is required, the electromagnetic lock 130 will accurately engage with the ratchet, effectively preventing unauthorized reverse rotation of the door even if there is an external force attempting to move the door body in the reverse direction.

[0032] The one-way access door described in the present application further comprises a driving mechanism, the driving mechanism comprising a driving unit 400 and a transmission shaft 410. The driving unit 400 has an output shaft 401, a first pulley 402 being provided on the output shaft 401, a second pulley 411 being provided on the transmission shaft 410, and the first pulley 402 and the second pulley 411 being connected and driven by a first synchronous belt 403. A first transmission wheel 212 is provided on the door shaft 210, and a second transmission wheel 412 meshing and assembled with the first transmission wheel 212 is provided on the transmission shaft 410. The design of pulley transmission ensures the synchronism and stability of power transmission, reduces energy loss and vibration during the transmission process, and improves the smoothness and efficiency of operation. An electromagnetic clutch 420 is assembled on the output shaft 401. Such a structural design enables the system to respond quickly as needed, achieving smooth power transmission and timely separation.

[0033] In this application, the linkage mechanism includes an eccentric plate 500, a connecting rod 510, and a sliding seat 520. The eccentric plate 500 is connected to the connecting rod 510, the connecting rod 510 is connected to the sliding seat 520, the sliding seat 520 is connected to the secondary door body 300, and a slideway 170 for the sliding seat 520 to slide is provided on the frame 100. The eccentric plate 500 is fixedly assembled with the second pulley 411. The linkage mechanism can drive the secondary door body 300 to move reciprocally through the rotation of the rotating door body 200.

[0034] The secondary door body 300 includes a reel 310, a rolling curtain 320 is wound on the reel 310, a door head 330 is assembled at the free end of the rolling curtain 320, and the door head 330 is connected to the sliding seat 520. The sliding of the sliding seat 520 can drive the winding of the rolling curtain 320 to realize the function of the secondary door. A third pulley 311 is assembled on the reel 310, a fourth pulley 140 is assembled on the frame 100, and the third pulley 311 and the fourth pulley 140 are connected and driven by a second synchronous belt 340. A belt clip 521 is assembled on the sliding seat 520, and the belt clip 521 is fixedly connected to the second synchronous belt 340. Compared with the design of the reel 310 provided with a torsion spring structure, this design has less requirement for the strength of the structure, can more effectively reduce the vibration and noise during the transmission process, ensure smooth operation, and improve the stability and reliability of the overall system.

[0035] In addition, the door head 330 is of a V-shaped structure, and the tip of the V-shaped structure is smoothly transitioned. The V-shaped structure can guide the movement of the door curtain more smoothly, and the smooth transition treatment reduces the risk of collision and increases the safety of use. A number of connecting rods 331 are provided at the top of the V-shaped structure of the door head 330, and the number of the connecting rods 331 is fixedly assembled with the sliding seat 520. This design enhances the connection stability between the door head 330 and the sliding seat 520. The rolling curtain 320 includes a number of curtain sheets hinged in sequence. The design of the hinged curtain sheets enables the rolling curtain 320 to flexibly bend when unfolding and rolling up, adapt to various opening and closing angles, and at the same time maintain good flatness, further optimizing the sealing performance and appearance of the door body.

[0036] Furthermore, this application also includes an anti-pinch mechanism, which includes a first anti-pinch member and a second anti-pinch member.

The door panels 220 include door frames 221 made of profiles, and glass plates 222 are assembled within the door frames 221. This makes the interior of the revolving door bright and well-lit, avoiding the uncomfortable feeling of being dark and cramped. The glass plate 222 is laminated glass. Even if the glass breaks, the fragments will be adhered to the film, and the surface of the broken glass remains clean and smooth. This effectively prevents the occurrence of events such as fragments stabbing and penetrating and falling, ensuring personal safety. The frame 100, the door body, and each transmission component of the present invention are all made of high-quality corrosion-resistant materials such as stainless steel or aluminum alloy, and are processed through precision machining to ensure the structural strength and durability under long-term use. In particular, for the door panels 220 of the revolving door body 200, their surface treatment not only considers aesthetics but also incorporates anti-fingerprint and easy-to-clean designs, effectively reducing the need for daily maintenance.

[0039] As another embodiment of this application, the frame 100 has a combined shape of a cylinder and a prism. The rotating area 110 is located within the cylinder, and the secondary door area 120 is located within the prism. Compared with the above embodiments, the shape of this embodiment is more concise. The cylindrical rotating area 110 ensures the smoothness and continuity of passage, while the prismatic secondary door area 120 provides a stable installation foundation and a more concealed storage space for the secondary door. The combination of the two presents a unique and harmonious visual effect.

[0040] The protection scope of the present utility model includes but is not limited to the above embodiments. The protection scope of the present utility model shall be subject to the claims, and any substitutions, deformations, and improvements that are easily conceivable by those skilled in the art to this technology shall fall within the protection scope of the present utility model.
